Spear (Yari) in Owari Kan Ryu 尾張貫流 (Kudayari & others)

Owari Kan ryū is known for its use of the kuda-yari (tube spear). The e (shaft) is run through a kuda (metal pipe) that’s in the front hand of the practitioner. Interestingly the school’s students start training by doing shiai (competition) and only after considerable training they learn the school's kata (forms). Most classical schools that practice shiai do so after learning kata. Thrusting using the kuda. Cross-stepping. Thrusting attack with kuda. Wide stance. Shiai. Shiai using a spear with a cross piece. The original demonstration from which these stills were taken is here:

The Structure of the Tenshinshoden Katori Shinto Ryu Syllabus

It should be noted that the current head, Otake Risuke, has commented that not all of the parts of Tenshinsho-den Katori Shinto Ryu survive. I recall his comments in various documentaries that Archery was once a component, and only some of the spear survives. Through various sources, mostly Otake's book, I have put together this brief outline of their syllabus, however I have little idea of the exact stage each is taught except that I believe the students start with Omote no Tachi. I will use this as the basis for further posts and may add to it over time. I believe their are important implications when Otake says that one of the main reasons for training all the weapons is to train the swordsman against them. Note in this section in brackets are my own comments and should therefore not be relied upon, those from the written work of Otake are clearly marked.
